The object of the invention is to provide lend the invention may be said to comprise the parts, improvements and combinations hereinafter described with reference to a preferred embodiment and set forth generically and specifically in the claims.

In the accompanying drawings, forming a part hereof:

Fig. 1 is a side elevation, the forward part of the vehicle bein broken away;

Fig. 2 s an enlarge vertical sectional view showing the separable means for driving the loader, the .parts being shown as if the vehicle body were sl' htly tilted; and

Fig. 3 is a sectional ont elevation, the plane of the section being 'ust. in front of the body and the drive for eloader.

Thenumeral 1 designates the chassis of a motor truck, and 2 its rear wheels. In the chassis is a longitudinal power shaft 3 driven from. the mg: (not shown that drives the vehicle. Y 's shaft may the driving shaft of the vehicle in advance of the transmission, or it ma be especial shaft connected with one of t epower take-ofis which are familiar in commercial trucks, the so arran ment in any event being such that this aft can be driven by the engine when the vehicle is at rest. Such matters being well known, l'eillllile no special illustration. Mounted on t e chassis is a tiltable, reardumping cargo body 4, having a top hinged rearate 5 adapted to swing rearward. The hinge connection permitting the body to ivot in this manner is illustrated at 6, "and the cylinder 7 is illustrative of any customary or suitable power means for uptilting the body to dischar e its contents. Carried as a er-o rated loa er, which is designated gen-r era y 8. In certain generic aspects of the invention this loader may be of different ty Specifically and preferably it comprises a track 9 and a car 10 movable t-here on from a int near the ground upward to dump its oad into the body 4, and back again. In the construction herein more specifically contemplated the track is disposed atone side of the body.

art of t e vehicle is a pow-p Proceeding now with a descrition of this c( nst1 'act1ou it will be observe that a longitudmal rail or w a 11 is arranged on the top of one of the $1 es of the body, this rail being engaged by grooved wheels 12 on a carnage which is formed bythe track rails 9 and by suitable connecting members 13. Additional, lateral rollers 14 on this hoistng and dumpin track carriage are engaged in a longitu lna channel 15 on the outside of the lower part of the side of the body,

brace the carriage against lateral tilting displacement either outward or inward. The track 9 is thus firmly sup rted on the tiltable body 4, yet can be s ifted forward or rearward along the side so that the material can be deposited in the bodylat various regions lengthwise thereof, thus distributing the loading.

The track rails 9 consist of channels go receive forward rollers 16 on the car 0. other rollers 17 thereon in rear of the roll era 16 traveling on the outer flanges of the channels. These rails extend substantially vertically upward from a point sufiiciently near the ground to the top of the side of the body, this portion of the track consequentf lilying close to the side of the vehicle. At t s top of the body side the rails are bent inward at an inclination carrying them well to. ward the center of the top .df the body; and atthis region the track rails are provided wlth inwardly rojecting dumping spurs 18 which diverge rom the continuations 19 of the rails, so that when the car is hoisted to this part of the track the rollers 16 travel in the spur rojections 18 while the rollers 17 proceed a dug the continuations 19, causing the car to be uptilted as indicated in dotted lines in Fig. 1. S ring bumpers 20 on the continuations 19 orm an abutment limit.- ing the. movement of the car in this posit1on.

The loader is shifted from time to time to cover the length of the body, and this. is accomplished by or sprocket chain 21 passing in longitudinal stretches along the lower portion of the side of the body 4', and about pulleys or sprocket wheels 22 mounted on said side near the opposite ends thereof. The upper stretch of this endless member is secured to a clip 23 means of an endless cable on the forward one of the track rails 9, and

the lower stretchis free. Thus, when the cable is operatedin one direction by a crank handle 24 connected to the rear pulley, the

loader is moved forward, and when the cableis operated in the other direction the loader is moved rearward. "In any position the loader is locked and held by means compris ing a dog 25 cooperative with a toothed .wheel 26 mounted with the rear pulley.

The car 10 is hoisted and lowered by means, of cables 27 which pass upward.

from the sides of the car to rotatable drums 28 journaled in brackets 29 on the upper end of the hoistin and dumping track carriage and movab e forward and rearward therewith. These drums are slidably splined on a longitudinal driven shaft 30 extending longitud' y over the top of the body and having suitab e fixed support upon the body 4 represented by an arm 31 of a forward gear bracket 32, w ereby it is held against longitudinal movement, the shaft being fixedly supported or not at the rear.

On the forward end of the shaft 30 is a gear 33, by which, through suitable inter- -mediate gears 34, it is driven from the u r end of a shaft 35 which extends vertica y downward at the front of the body by which it is carried, the shaft being journaled in the bracket 32 referred to and in another bracket 36 on the. lower portion of the body. The lower end of this shaft carries a friction cone clutch member 37 The complementary, driving member 38 is on the upper end of a short vertical shaft 39 projecting upward from ,a gear-case 40 mounted in the chassis, this shaft being driven by the shaft 3 through suitable cars 41. This friction. member is all ably splined on its shaft, so as to be capable of yielding when the body 4, after having been tilted to dump, is lowered to its normal position bringing the member 37 down on the member 38, and is sustained by a spring 42 so as to reduce a drivin engagement. The cone c utch elements t us constitute embodiments of se rable driving and driven elements carried by the chassis and tiltable body respectively, permitting the bed and loader to be tilted awa from the mechanism on the chassis, and w ereby the members harmlessly re-engage so that the loader can be driven when the body is down. They also afiord a clutch for throwing the powe'ron and ofi the loader at the proper times, 'a means for holding the car at the top in dumping position for the necessary brief riod, and a means for efl'ecting control] lowering of the car. To theseends means are rovided for shifting the clutch member 38hy the attendant, the said means being shownv as oomprisingb:

understood as passing to a handle or edal at asuitable. point. When the car is rought up against the bumpers 20 the clutch automatically slips, so that injury is prevented and the power merely serves to hold the car upturned a ainst the buffer. Then after the car has eposited the ashes or other material in the body, the operator moves the clutch member 38 very slightly against the action of the spring, so that the clutch slips more freely, permitting the car to descend, the rate of such descent being very easily controlled by the operator regulating the friction between the driving member turning in one direction and the driven member rotated by the weight of the car in the op posite direction.

The top of the body 4 is provided with a suitable cover 45 to restrain flyin ashes or the like, this cover being arrange to leave a necessary opening along the side where the car discharges its material. In order to close this opening as much as may be, extensible and contractible closures are pro vided at opposite sides of the loader and connected thereto, so that when the loader is moved forward or rearward one closure automaticaly extends and the other shortens, and vice-versa. These closures may take the form, for example, of flexible strips 46 substantially the width of the opening, adapted to be woundand unwound u on spring shade rollers 47 mounted at t e opposite ends of the body, the strips extending from these rollers toward the track rails 9, to which their ends aresecured.

The operation will be briefly summarized. The vehicle having reached a point of collection is brought to rest, and the car 10 is lowered to the bottom of the track 9. The engine is to be understood as running and rotating the shaftf3. The clutch member 38 is held out while the car is receiving its load, and then put into drivin engagement with the complementary member 37. This causes the car to be hoisted to the top of the track and there upturned so that its contents fallinto the body. The clutch slips at this time, and next the operator causes the clutch to slip further so that the car runs down the track under the control of the operator. The car is reloaded and the opera tion is repeated. When one portion of the interior of the body becomes sufliciently filled, the loader is moved to a new point along the side of the vehicle, and this may be done several times so that the body becomes evenly filled from frontto rear. YVhen the body has been sufiiciently loaded the 've-. hicle is driven to the appropriate spot, the rear gate unlocked, "and the body uptilted to dump. In this operation the drive for the hoist separates at the clutch members 37, 38, the clutch member 37 rising away from the member 38. On again lowering the body the visions whereby separable arts for drivingy from the power the hoist on the tiltable means in the chassis of the vehicle are safeguarded from in'u to themselves and other plilirtshwhen all: byy is lowared down onto t e c assis, w are proper rivmg engagement is then insured, and this even though there may be some natural variation in the ition of the body ugror down, and wheregins loader and the iving-mechanism are safeguarded from injury, at the moment of dumping the contents of the car or bucket into the body, or at any time when the operation of the hoist may be obstructed by the refuse or otherwise, through the automatic.

action of the slippage connection betweenthe ower means and the hoist.

ile the referred'einbodiment of the invention has described in detail, it will be understood that numerous other and specifically difi'erent embodiments are possible, and I do not therefore wish to limit myself to the precise construction illustrated.
